FLOAT-VALVE.

ings, forminga part of the same.

This invention relates to certain improvements in float valves for flushing tanks, and lever mechanism for operating gthe same.

It is the object of the invention to provide an automatic valve whichshall be simple in construction, and the `leverniechanism. for operating whichis so arranged as to obtain alarge leverage at the `point of closing `and of opening, so as to easily start the valve iu opening and render itcertain of closing, in combination with a quick action and large movement of the valve. Aconstruction for effecting these objects is shown` in the 1aecompanyin drawings, `to `which reference may be had in connection with the `following descriptionfor a complete understand.

ing of the invention.`

In these drawings- Figure l is a side view of an `improved ioat valve .operatingmechanism `with float attached, `the parts being shown positioned in; a flushing` tankwhich is shown in section, and partly broken away and with the valve closed,the position of the float with the valve open being shown .in dotted llines. Fig'. 2 `is a; vertical section taken on line 2f-21of `Figwl,` showing the preferred construction of valve; Fig. 3 is a` top view of the valve operating mechanism showing the connection to the valve spindle; Fig. 4 is a detail sectiontaken on linear-f4 of Fig.` 1, and Fig.` 5 is a detail, partially in. section, of the levermechanismfor operating the valve, the parts being shownin the position assumed when lthe valve is` open;

Referring now to these drawings, the valve and operating mechanism therefor is shown as mounted in a flushing tank A ofi any suitable or usual construction. `The inlet pipe 10 passes through the bottom of the. tank and is provided with a flange 11 adapt;

`ed to bear against the inside `bottoniof ithel tank. Suppy pipe 10, where` it passes through the tank,1is threaded and provided with `a nut 12 by screwingl up `which `the flange 11 is drawn `against .the bottom oi" the tank forming a `tight connection. The` end of the pipe `10 projects. into the tank,

and above the flange 11 is threaded andzhas screwed thereon a fitting H13 which has screwed therein at its upper end a tubular member or sleevelt. The valve 15 is se-` cured on the lower end of a valve spindle 16 and seats `on a valve seat 17 on the `end of the inletpipe 10, a washer 18 `beingprovided between the valve seat 17 and the end. of the pipe. This construction is. a desir` able one as byiit thevalve seat is readily accessible `and removable.

The fittingl 13 is provided with a delivery opening` `19 and on the opposite end is or may be provided `with a boss `20 into which may be secured, if desired,an afteriow 211.1

At its upper end the valve spindle is screwed or otherwise suitably secured in a iitting 25.

In the best constructions and as shown the valve sleeve 1s provided above the valve with pressure relieving means, these means.` actingto release any liquid under pressure Ipassing upy into member 14 past the loose` valve 15, which otherwise might be forced out of the top of the sleeve. In the particu-z lar construction illustrated, these pressure relieving means comprise suitable apertures` Q6 in the walls of the member 14, through` which suchl pressure liquid will be dis` charged into the tank.

Tlie lever `mechanism for operating the valve may beivariously constructed and sup# ported.` It will, however, be of such char.-

acteras before indicated as to provide a large leverage at the point of closing `and opening and so as to start the valve in open.

ingaiid render its closing very effective..

Preferably, furthermore, this lever `mecha-1` nism will be so supported that the relation of the valve to the float `may be` adjusted. readily and simply.

In the construction illustrated, the fitting i 25` before referred to, in which the upper end of the valve spindle is mounted,` is provided with a pin 30 onwhich works the forked end` 31 of a lever 32, this levera32 1 operating the valve spindle. This lever .32 and the other` parts of the lever mechanism hereinafter described are carried so that the justedeasily and accurately, and to this end 1 there is provided a split band 33 encircling 1 the top of ithe valve sleeve, this split `band bein ;adjustable vertically on the sleeve,`

relation of `the valve to the ioat may be ad` suita le means,`as screw 34, beingprovided fontightening the band` about the sleeve.`

On this band 331are supported the various "end of a forked lever 39.

arm 39 is suitably connected by a head rod 4,movement of the float, the'support is proi vided With a bracket 43 -invvhich is located i operating parts of the lever mechanism for operating the valve. In the vpreferred construction, and as shown, the ends ofthe split band 33 are extended'outvvardly from the sleeve forming extensions 35 which form a support. The .lever 32 before referred to is pivoted in this support at 36. The end of this lever Aopposite the end secured to the valve spindle is provided With a slot 37 Pivoted at `38 in the extensions 35 is oneV Bet-Ween theV forked ends ofthe lever 39 is so mounted ay pin40 as to 'lie in the slot 37 of lever 32E before referred to. Ther other end of lever 41 to a float 42. To limit thefdownward;`

a suitable stop, as set screw 44, this set screw bearing against the underside of lever 32` as shown in Fig. 5.

yWith the construction described, it is obvious that a very eiective and certainopening and closing of the valve is secured, the pin Working in the slot of the valve spindle levery affording aimaximum'leverage at the point of opening and closing. While the detail construction shown has been found particularly effective for the .purpose for which it is designed, it Will be understood that certain changes and variations may be made in it Without departing from the invention.

What I claim is l. The combination of a tubular member, a support adjustable on the said member, a valve spindle, a lever arm connected at one end With the valve spindle, pivoted in the support `and provided With'ya slot at its oppositeiend, and a second lever pivoted on the supporty and having a pin Working in the slot of the first lever to vary the lever- Copies of this patent may be obtained. for five cents age during the valve movement,-the second lever `at the end opposite the pin being `connected With a float.

2. In a float valve, the combinationvvith the valve and valve spindle, of alever arm n pivoted in ia fixed support and connected at one end with the valve spindle and uprovided with a slot in its opposite end, and a second lever pivoted on t-he support and havinga pin Working in the slot of the first lever to varyj the leverage during the valve movement, and connected zat the end opposite the pin With a float. y

3. The combination of a tubular member, 1

a support on said member, a lvalve spindle, a lever pivoted in the support and connected at one end with the valve spindle and provided With a slot at its opposite end, and a second lever having a pin mounted to Work in the slot in the first lever to vary the lever-` age during the valve movement, and con` nected at' the endy opposite the pin with a float. f

4. The combination ofy a tubular member, a split ring encircling said lmember Vat the top, the ends of the ring being extende'd'to form a support, a valve spindle, a lever arm i: Y'

connected at one end With the valve spindle and pivoted in the support, a'slot in the opposite end of the lever, and `a second lever provided With a` pin and pivoted pso that the pin Works in the slot Aof Athe first lever .to vary the leverage during the valve movement.

In testimony whereof, I havehereunto'set 'i il my hand, in the presence of'tvvosubscribing Witnesses. l
